To all whom it may concern:

Be it-know'n that l, REUBEN B. BENJAMIN,

' acitizen of the United States,- residing at Chicago, in the county of 600k and State of aElillOiS, have invented new and useful Improvements in \Qutlet-Boxes, of which the follbwing is a full, clear, concise, and exact description, reference being had to the acconipanying drawing, forming a part of this specification.

invention relates to outlet boxes such as are employed where it is desired to con-f nect'translating devices with conduit-protected electrical conductors, and resides in ,novel and "advantageous features of con st-ru'ctiodand arrangement, whereby an improved devicefpr the purpose described is obtained.

Outlet boxes of the class to which my .vention relates, aretor the purpose of protecting the translating devices, such 'as in-' candescent', lamps, and their rangements consisting of many parts, were necessarily employed; My invention how-..

ever, provides a device which does not have these' disadvantages, being" constructed of simple and easily assembled :parts,

which thoroughly protects the translating devices against destructive extraneous conditions.

..-Tl e o,i itlet box. of my .inventioinis illus 'tia'ted'i'n the accompanying drawings, in

Figure 1 is an elevational view thereof; Fig. 2 is acentral longitudinal sectional view on the line 2 2 "of Fig. 3, looking in the direction indicated by the arrows; Fig. 3 is a plan view; Fig. 4 is a view of the under side thereof, parts being removed to disclose the construction; Fig. 5 is a sectional view similar to that of Fig. 2, illustrating modifications within the scope of my invention; and Fig. (l is a similar sectional view illustrating another modification.

The device consists primarily of the easasso ciated arrangements against severe weather ng, moisture and other destructive cond1t1ons,:,

ing 10, of cast iron or other durable material, which is adapted tovbe placed in the path of the electrical conductors with which it is desired to connect the translating de- =vice. These conductors, indicated at 11, 11 in the drawings, are disposed within protecting conduits, which, as shown at 12, 12, 'Fmay be pipes of iron or other substantial imaterial', which as particularly illustrated in Figs. .1 to at inclusive lead into thecasing lneans of screws 15, 15 passing through apertures therein and having threaded en- 'gagement with the casing, a rubber gasket 16 being disposed between the cover and the pasing to effectively exclude moisture from the'box. 'As these devices are, in their ordinary usage, for the purposeot accommodating incandescent lamps, a lamp receptacle {1? is secured'to the inner side of the cover 14, in register with the opening 18 therein,

by means of screws 19, 19 passing through the cover and engaging in threaded openings-in the porcelain casing of the receptacle. The circuit conductors 11, 11 are conhected with the terminals of the receptacle 17 as indicatedat. 20 in the drawings. suitable glass casing 21 is provided for the protection of the incandescent lamp, and

has threaded engagement with a-support-ing member-22 which has the inwardly extending flange 23, clamped between the cover-14 and the rubber gasket 16. A washer 24 is placed. within the supporting member22 in such a manner as to be clamped securely therein when the glasscasing 21 is screwed into the supporting 'memberpthus assisting in securing a thoroughly protective arrangement. I

It is usually desirable to employ reflecting means for well known purposes, and I have shown means whereby a reflector may be properly and conveniently. accommodated. An annular supporting member 25 is clamped between the heads of the screws 15 and the cover 14 and is pro vided with an extending rim flange 26 which is crimped at 27 as indicated in the drawings to accommodate a spring wire 28 to which is secured the rellector 2t), suitably disposed relative to the incandescent lamp 30. inserted into the receptacle 17. The spring wire is split at Ell to admit of its ready removal and its adjustment into any desired position so as to most advantageously reflect the light.

It freruiently occurs, when an outlet box is desired to be. connected with the conduit, that the immediate surroundings are such as to prevent. free mani mlation of the de rice and of tools to secure the joint between the casing and the conduits illustrated in Figs. 1. to 4. llhen occasion arises where such; a joint would be impracticable the construction shown in Fig. may be employed. In this arrangement the pipe 12 is not threaded into the opening in the casing but is merely disposed proximate thereto, suitable means being provided to hold the same in place and to form a moistore-proof joint. The sleeve threaded on the pipe 12 and is adapted to be manipulated. to tirmly clamp the gasket 2-33 against the face (rt-the. annular boss 3-}; about the opening provided in the casing. The sleeve 32 hasa collar 33.3, and a clamping cap member St; is threaded on the outside oi the boss ill and engages the collar 35 to clamp the same against the boss, thereby securing an etiieient moisture-proof joint. lt evident that the parts are easily manipulated and. the joint can be employed even though the position of the outlet box he an inconvenient one,

In Fig. 5 l have also illustrated a modification. which provides for the attachment of a shade instead of a globe, for the incandescent lamp. A supporting plate 37 is clamped between the heads of the clamping screws 15, 15 and the cover 14:, and is proi'ided with the center opening 38' into which extends the flange portion 35) of the shade holder 40, this tlangc portion being burred over as indicated at 1-1 in the drawings to rigidly secure the shade holder to the supporting plate. The shade holder is pro vided with the thumb screws &2, as is usual in the art, to retain in place a suitable shade t3.

In Fig. (3 I have shown another modification for accommodating a shade. In the arrangement illustrated in this figure the supporting inembeiwbl is" clamped between the cover 14 and the gasket 16. The rim flange of this supporting member is provided with the thumb screws to support the shade in an apparent manner:

I claim as new and desire to secure by Letters Patent:

1. In an outlet box, the combination with a casing, of a cover therefor, a lamp receptacle supported in the casing. and a globe support clamped to the casing with said cover. I

In an outlet. box, the combination with a casing, of a cover therefor, and a globe support and a rellector support clamped with said cover to the casing.

33. in an outlet; box, the combination with a casing, of a cover therefor, a globe support and a reflector support clamped with said cover to the casing, and a lamp receptacle secured to said cover.

4t. in an outlet box,,the combination with a casing, of a cover therefor, a globe support, a. reflector support and a screw passing through said reflector support, globe support and cover, and having threaded engagement with said casin 5. In combination, a casing having openings for the admittance of conductor wires, of a cover for said casing, a lamp receptacle secured to said cover, a globe support; clamped to said casing with said cover, a globe supported thereby, a gasket disposed between said globe support and said casing, a reflector support clamped to said cover, and a reflector supported thereby.

In witness whereof, I have hereunto subscribed my name in. the presence of two witmesses.
